Ad hoc networks consist of a number of devices equipped with one or
more wireless interfaces, which cooperate to provide wireless
communications among them. Nodes which are not in the radio range one
each other, use other intermediate nodes as relays to find multi-hop
paths towards a destination.

Unlike ad hoc networks, in sensor networks the devices are usually
static. However, the way they work based on off, on and iddle states,
makes the topology variable. In addition, usually available resources
are lesser, and the scalability of the solutions becomes a very
important factor. This creates the need for localized algorithms rather
than global or centralized ones.

Context Aware Adaptive applications are those who are able to modify and adapt their operation to their environment.

In particular, adaptive multimedia applications are a subset of
those applications, which are able to adapt their internal components
(e.g. audio and video codecs, rates, etc.) to maximize the user's
satisfaction in terms of perceived quality. To make that decission they
use information from their environment called context.

Network, service and application management today faces numerous
challenges, ones that older ways of doing things cannot solve. The
concept of policy-based management (PBM) addresses some of these
problems and offers possible solutions.

It provides a system-wide view of the network and its services and
applications, and shifts the emphasis of network management and
monitoring away from specific devices and interfaces towards users and
applications.

The objective of this line is extracting useful knowledge from large volumes of
information. We design and improve techniques of Data Intelligent
Analysis and of Optimization to apply them to real problems of the
logistic, economic-financial, bioinformatics type, and the
obtained models serve to understand better the behaviour of the
problems and act of more real way.

This line is focused on the study of techniques for coordination and
adaptiveness of ubiquitous services. In this manner, complex
systems compound by a large number of autonomous entities
coordinate in a suitable manner. Besides, in this line
adaptiveness of such autonomous entitites is studied. They are
modeled by means of behaviour patterns.
